Graphitic Cast Steel Rolls
The graphitic steel rolls have a metallographic structure consisting of carbides and a small amount of graphites in the pearlitic matrix. The rolls of this material has better tensile strength and better resistance to thermal cracking than adamite rolls of the same hardness, and the wear resistance of which is better than the cast steel rolls. Graphitic steel rolls are mainly used in the BD mill and roughing stand of hot rilling mills, sections mills, tube mills, bar mills and wire mills.
